Sequel to Grand Unified Theory -1
Despite all his greatest achievements, Einstein wasn't satisfied. He was still looking for the ultimate answer. So he set on a goal to achieve this by relating his new picture of gravity ( General Relativity) with Electromagnetism(EM). During the early 19th century, Electricity and magnetism were scientists great interests. Both Electricity and magnetism played an important role together and was also helpful in further telecommunications systems. It was so important that it demanded a specific unification. For instance, if suppose you are in a hill station during a thunderstorm you will probably get the idea of how electricity and magnetism are closely related. i.e the thunder strike creates a magnetic field that will show abnormal functions in your compass. This field was unified as the electromagnetic field and was developed using the language of mathematics. How fascinating is it to see just a four line mathematical expression showing the relation b/w electricity and magnetism. This equations were deduced by Maxwell. Just as how Newton revolutionized physics with Gravitation, Maxwell has equally helped in understanding our universe. Einstein believed that this unification of both his view of gravity and electromagnetism would give birth to the answer to everything. This step was the first try on understanding our universe completely. He was one of the physicists who wanted to know the mind of God(entire picture of our universe). In fact this is the goal of today's string theorists; To unify almost everything within one simple theory - From the big bang to the black holes.
As Einstein started working on his theory he found a major problem in unifying it, he noticed that there was a huge difference b/w the strength of the Electromagnetism and Gravitation. i.e the strength of EM force being far more stronger than the gravitational force. Wait! How is that even possible? Gravity is so strong that its even capable of bending light! Gravity probably should be the strongest force. Yes, that is partially right but it is a known fact that it is certainly not as much stronger than EMF(Electromagnetic Force). In fact EMF is billions time stronger than gravity. The reason behind this lies in the microscopic level and is also the reason why we don't fall right down into the center of the earth. It might seem quite strange but its the truth. Everything in our universe is made up small bits of atoms, in which the -ve electric charges are present in the outermost shell of the atom. Now remember, the force which keeps you on the earth's surface is EMF, because there is a strong repulsive force between the two -ve electric charges.(One being the electric charge of yourself and the other being the earth's surface's charge). Imagine the repulsive force created to sustain almost each and everything in our earth. In layman's language, we all know that gravity pulls you down to the earth. But guess what now you know that EMF creates a massive repulsive force which prevents the gravitation pull towards the earth. Now, do you think gravitational force is much stronger than EMF? No, certainly not. This was the underlying reason for the major problem in unifying them both.
